Multicenter StudyCardiovascular Health in Young Adulthood and Association with Left Ventricular Structure and Function Later in Life: The Coronary Artery Risk Development in Young Adults Study.
The aim of this study was to determine the association between cardiovascular health (CVH) in young adulthood and left ventricular (LV) structure and function later in life. ⋯ Greater levels of CVH in young adulthood are associated with lower LV mass and lower risk for diastolic dysfunction 25 years later.

Impact of Body Size on Inferior Vena Cava Parameters for Estimating Right Atrial Pressure: A Need for Standardization?
Inferior vena cava (IVC) diameter and its respiratory change, as determined using echocardiography, are commonly used to assess right atrial pressure (RAP). Despite the widespread use of the IVC approach for RAP assessment, the relations among body surface area (BSA), IVC diameter, and respirophasic change remain unclear. The aim of this study was to investigate the impact of BSA on IVC parameters for predicting elevated RAP. ⋯ Body size, measured as BSA, is important to consider when IVC diameter is used to assess RAP. The optimal cutoff point of IVCDmax was 21 mm for patients with larger BSAs and 17 mm for those with smaller BSAs. However, the cutoff point of IVC collapsibility was not influenced by the difference of BSA.

Correction of Doppler Gradients for Pressure Recovery Improves Agreement with Subsequent Catheterization Gradients in Congenital Aortic Stenosis.
In congenital aortic stenosis (AS), suboptimal agreement between Doppler-derived gradients and catheterization gradients may lead to inappropriate referrals for catheterization. To address this problem, the authors investigated whether adjusting Doppler gradients for pressure recovery (PR) improved their agreement with subsequent catheterization gradients. ⋯ In congenital AS, correcting the peak Doppler gradient for PR significantly improved agreement with the subsequently measured cath gradient. This approach may improve decisions regarding referral for catheterization.
